The first lamp holder 272 a includes a first wing portion 71 and a second wing portion 72 that is integrally formed with the first wing portion 71 so as to hold a portion of an outer face of the first lamp 211.

In this exemplary embodiment, the second lamp holder 272 b has structure substantially identical to the first lamp holder 272 a, and thus a detailed description of the second lamp holder 272 b will be described.

The second lamp holder 272 b receives a second lamp 212 of the lamps 210 so as to fix the second lamp 212 to a predetermined position.

The supporting portion 273 is disposed between the first and second lamp holders 272 a and 272 b. The supporting portion 273 is protruded from the base body portion 271 toward a direction where the first and second lamp holders 272 a and 272 b are protruded so as to support the diffusing plate 220. The supporting portion 273 has a coupling protrusion 73 disposed at a position spaced apart from the base body portion 271 and protruded toward a longitudinal direction of the base body portion 271. When the supporting member 270 is inserted into the opening of the receiving container 260, the coupling protrusion 73 is coupled to the upper face of the receiving container 260, thereby preventing the supporting member 270 from being separating from the receiving container 260.

Referring to FIG. 3, the reflecting plate 240 has a first engaging opening 241 formed through the bottom thereof and a second engaging opening 242 formed through the bottom thereof. The first and second lamp holders 272 a and 272 b are inserted into the second engaging opening 242, and the supporting portion 273 is inserted into the first engaging opening 241. The second engaging opening 242 has a first holder engaging opening 242 a through which the first lamp holder 272 a is inserted and a second holder engaging opening 242 b through which the second lamp holder 272 b is inserted. The first engaging opening 241 is disposed between the first and second holder engaging openings 242 a and 242 b.

The receiving container 260 includes a bottom plate 261 on which the reflecting plate 240 is disposed and a sidewall 262 extended from an edge of the bottom plate 261 to provide a receiving space. The receiving container 260 includes a first opening 263 formed through the bottom plate 261 thereof and a second opening 264 formed through the bottom plate 261 thereof. The first opening 263 is formed at a position corresponding to the first engaging opening 241 and the second opening 264 is formed at a position corresponding to the second engaging opening 242.

The second opening 264 has a first holder opening 264 a and a second holder opening 264 b corresponding to the first and second holder engaging openings 242 a and 242 b, respectively. Numbers of the openings formed through the receiving container 260 are identical to numbers of the engaging openings formed through the reflecting plate 240.

The supporting portion 273 is inserted inside the receiving container 260 after sequentially passing through the first opening 263 and the first engaging opening 241. The coupling protrusion 73 of the supporting portion 273 is inserted inside the receiving container 260, and coupled to the bottom plate 261 in a hook-type manner. In this exemplary embodiment, the first opening 263 has a width D1 that is smaller than a width D2 at which the coupling protrusion 73 is formed. Thus, the supporting portion 273 inserted inside the receiving container 260 may be not separated from the receiving container 260 by the hook-type manner of the coupling protrusion 73 and the receiving container 260.

Although not shown in FIGS, a width of the first engaging opening 241 may be identical to or greater than the width D1 of the first opening 263. In case that the width of the first engaging opening 241 is greater than the width D1 of the first opening 263, the width of the first engaging opening 241 is identical to the width D2 at which the coupling protrusion 73 is formed. Thus, the coupling protrusion 73 may be coupled to the reflecting plate 240 in the hook-type manner.

The first lamp holder 272 a is inserted inside the receiving container 260 after sequentially passing through the first holder opening 264 a and the first holder engaging opening 242 a. The second lamp holder 272 b is also inserted inside the receiving container 260 after sequentially passing through the second holder opening 264 b and the second holder engaging opening 242 b.

FIG. 4 is a plane view showing the backlight assembly shown in FIG. 2. In FIG. 4, in order to clearly show the reflecting plate 240 and the supporting member 270, the diffusing plate 220 and the receiving container 260 are omitted.

Referring to FIG. 4, when the reflecting plate 240 is combined with the receiving s container 260, the first lamp holder 272 a of the supporting member 270 is disposed on the reflecting plate 240 after sequentially passing through the first holder opening 264 a of the receiving container 260 and the first holder engaging opening 242 a of the reflecting plate 240. The second lamp holder 272 b of the supporting member 270 is also disposed on the reflecting plate 240 after sequentially passing through the second holder opening 264 b of the receiving container 260 and the second holder engaging opening 242 b of the reflecting plate 240. The supporting portion 273 of the supporting member 270 is also disposed on the reflecting plate 240 after sequentially passing through the first opening 263 of the receiving container 260 and the first engaging opening 241 of the reflecting plate 240. The base body portion 271 of the supporting member 270 is disposed under the receiving container 260 and the reflecting plate.

That is, the first lamp holder 272 a, the second lamp holder 272 b and the supporting portion 273 are disposed on the reflecting plate 240, but the base body portion 271 is disposed under the reflecting plate 240.

In other words, the first and second lamp holders 272 a and 272 b holding the first and second lamps 211 and 212 and the supporting portion 273 supporting the diffusing plate 220 of the supporting member 270 are disposed on the reflecting plate 240, and the base body portion 271 is disposed under the reflecting plate 240 of the supporting member 270.

The first lamp holder 272 a and the second lamp holder 272 b and the supporting portion 273 disposed on the reflecting plate 240 are fixed to the receiving container 260 by the hook-type manner between the coupling protrusion 73 protruded from the supporting portion 273 and the receiving container 260. Thus, an area of the reflecting plate 240 covered by the supporting member 270 may be reduced.

As a result, an area of the reflecting plate 240 that reflects the light emitted from the lamps 210 may increase, and the reflecting plate 240 may uniformly reflect the light over the whole area thereof. Thus, the backlight assembly 200 may provide the light having uniform light distribution to the liquid crystal display panel 100 so that the flat panel display apparatus 500 may improve display quality of the image displayed thereon.

FIG. 5 is a cross-sectional view showing a backlight assembly according to another exemplary embodiment of the present invention.

Referring to FIG. 5, a backlight assembly 600 according to another exemplary embodiment of the present invention has same structure as the backlight assembly 200 shown in FIG. 2 except for a reflecting plate 610, a supporting member 620 and a receiving container 630.

The backlight assembly 600 includes a plurality of lamps 210, a diffusing plate 220 that diffuses a light emitted from the lamps 210, the reflecting plate 610 that reflects the light from the lamps 210 to the diffusing plate 220, the supporting member 620 that uniformly maintains an interval between the lamps 210 and the diffusing plate 220 and the receiving container 630.

In FIG. 5, the lamps 210 have a first lamp 211 and a second lamp 212, but the flat panel display apparatus 500 may have substantially more than two lamps.

The first and second lamps 211 and 212 are arranged in parallel to each other so as to uniformly provide the light to the liquid crystal display panel 100 (not shown, refer to FIG. 1). The first and second lamps 211 and 212 are spaced apart from the diffusing plate 220, and each of the first and second lamps 211 and 212 is spaced apart from each other in a predetermined interval.

More particularly, the diffusing plate 220 is disposed on the first and second lamps 211 and 212, and the reflecting plate 610 is disposed under the first and second lamps 211 and 212.

The reflecting plate 610 has a plurality of engaging openings into which a portion of the supporting member 620 is inserted.

A remaining portion of the supporting member 620 is disposed under the reflecting plate 610. The supporting member 620 has a base body portion 621, a plurality of lamp holders 622 that fixes the first and second lamps 211 and 212 to a predetermined position, and supporting portion 623 that supports the diffusing plate 220.

Particularly, an upper face of the base body portion 621 disposed under the reflecting plate 610 makes contact with a lower face of the reflecting plate 610.

The lamp holders 622 are protruded from the upper face of the base body portion 621. The lamp holders 622 have a first lamp holder 622 a and a second lamp holder 622 b. In this exemplary embodiment, the supporting member 620 has two lamp holders, but numbers of the lamp holders may be varied in accordance with numbers of the lamps 210.

The first lamp holder 622 a receives the first lamp 211 of the lamps 210 so as to fix the first lamp 211 to a predetermined position. The first lamp holder 622 a includes a first wing portion 61 and a second wing portion 62 that is integrally formed with the first wing portion 61 so as to hold a portion of an outer face of the first lamp 211.

In this exemplary embodiment, the second lamp holder 622 b has structure substantially identical to the first lamp holder 622 a. Thus, a detailed description of the second lamp holder 622 b will be omitted.

The second lamp holder 622 b receives the second lamp 212 of the lamps 210 so as to fix the second lamp 212 to a predetermined position.

The supporting portion 623 is disposed between the first and second lamp holders 622 a and 622 b. The supporting portion 623 is protruded from the base body portion 621 toward the diffusing plate 220 to support the diffusing plate 220.

The first lamp holder 622 a, the second lamp holder 622 b and the supporting portion 623 are inserted through a plurality of engaging holes formed through the reflecting plate 610 toward the diffusing plate 220.

The reflecting plate 610 has a first engaging hole 611 into which the supporting portion 623 is inserted and a second engaging hole into which the first and second lamp holders 622 a and 622 b is inserted.

The second engaging hole has a first holder engaging hole 612 into which the first lamp holder 622 a is inserted and a second holder engaging hole 613 into which the second lamp holder 622 b is inserted. The first engaging hole 611 is disposed between the first and second holder engaging holes 612 and 613.

The reflecting plate 610 and the supporting member 620 are received into the receiving container 630. In order to receive the base body portion 621 of the supporting member 620, the receiving container 630 has a receiving recess 31 formed at a bottom plate thereof. The receiving container 630 may prevent separation of the reflecting plate 610 from the bottom plate of the receiving container 630.

An adhesive member 640 is disposed between the base body portion 621 of the supporting member 620 and the receiving container 630. The adhesive member 640 adheres the base body portion 621 of the supporting member 620 to a bottom face of the receiving recess 31 to improve coherence between the supporting member 620 and the receiving container 630.

FIG. 6 is a plane view showing the backlight assembly shown in FIG. 5. In FIG. 6, in order to clearly show the reflecting plate 610 and the supporting member 620, the diffusing plate 220 and the receiving container 630 will be omitted.

Referring to FIG. 6, when the supporting member 620 is coupled to the reflecting plate 610, the first lamp holder 622 a and the second lamp holder 622 b of the supporting member 620 are disposed on the reflecting plate 610 after passing through the first holder engaging opening 612 and the second holder engaging opening 613 of the reflecting plate 610. The supporting portion 623 of the supporting member 620 is also disposed on the reflecting plate 610 after passing through the first engaging opening 611 disposed between the first and second holder engaging openings 612 and 613 of the reflecting plate 610.

That is, the first lamp holder 622 a, the second lamp holder 622 b and the supporting portion 623 are disposed on the reflecting plate 610, but the base body portion 621 is disposed under the reflecting plate 610.

In other words, since the base body portion 621 of the supporting member 610 is disposed under the reflecting plate 610, an area of the reflecting plate 610 covered by the supporting member 620 may be reduced. As a result, an area of the reflecting plate 610 that reflects the light emitted from the lamps 210 may increase, and the reflecting plate 610 may uniformly reflect the light over the whole area thereof. Thus, the backlight assembly 600 may provide the light having uniform light distribution to the liquid crystal display panel (not shown).

FIG. 7 is a perspective view showing the receiving container shown in FIG. 4.

Referring to FIG. 7, the receiving container 630 has a bottom plate 631 on which the supporting member 620 and the reflecting plate 610 are sequentially disposed and a sidewall 632 extended from an edge of the bottom late 631 to provide a receiving space.

Particularly, the receiving recess 31 is formed at the bottom plate 631 of the receiving container 630 so as to receive the base body portion 621 of the supporting member 620. The receiving recess 31 is formed by partially recessing the bottom plate 631 of the receiving container 610. Thus, the bottom plate 631 of the receiving container 630 corresponding to the receiving recess 31 is outwardly protruded such that a receiving space of the receiving recess 31 may be sufficiently obtained. As a result, the receiving container 630 may prevent separation of the reflecting plate 610 from the bottom plate 631 of the receiving container 630. In this exemplary embodiment, a depth of the receiving recess 31 is substantially equal to a thickness that is a sum of thicknesses of the base body portion 621 and the adhesive member 640.

According to the present invention, the backlight assembly has the lamps, the reflecting plate disposed under the lamps and the diffusing plate disposed on the lamps. The backlight assembly also further has the lamp holder uniformly maintaining the interval between the lamps and the supporting member having the supporting portion supporting the diffusing plate. The reflecting plate has the engaging openings, the lamp holder and the supporting portion inserted through the engaging openings, and the base body portion integrally formed with the lamp holder and the supporting portion is disposed under the reflecting plate.

Thus, the area of the reflecting plate covered by the supporting member may be reduced. Therefore, the flat panel display apparatus may enhance an amount of the light reflected from the reflecting plate and uniformity of the light, thereby improving the display quality of the image.
